Law Firm Office Openings in 2026 Held Flat as Lateral Hiring Rose

Law firm new office openings 2026 figures point one way: firms are adding lawyers faster than they are adding addresses. Sartori & Partners data show that firms announced 123 office openings in the 12 months to October 2026. Over a comparable year, lateral moves between law firms rose 9.0%, from 13,128 to 14,305. Announced openings did not follow. Their year-on-year count held flat (-3.1%). For a managing partner weighing a new office against more hires in the offices the firm already runs, that gap is the starting point.

The two measures moved apart over the past year. In the Sartori & Partners lateral database, moves between firms rose 9.0% on the settled 12-month windows, and partner moves rose 8.4%, from 3,558 to 3,858. Office openings, counted from public firm announcements, came to 123 over the 12 months to October, and year on year the count held flat (-3.1%).

Scale explains why the gap matters. Over the same 12 months there were 114.6 lateral arrivals for every announced opening. Even if each new office opened with a sizable group, most lateral hires still joined offices that were already open. More hiring with steady openings means the added lawyers went to existing platforms. The contest for a lateral partner is therefore fought mainly between established offices in the same city, not against a stream of new entrants.

Firms announced 132 openings in calendar 2025, the highest annual count since the series begins in 2022. The yearly counts are a record of announcements, not a growth curve. Earlier years were collected from fewer firms, so the movement from one year to the next says little about how fast firms expanded. So far in 2026, firms have announced 106 openings, and the year is not complete. The fair comparison is year on year over 12 months, where the count of openings held flat (-3.1%).

The lateral series gives the other side of the picture. Calendar 2025 was also the largest full year for lateral moves, at 13,237, and 2026 has already reached 12,554 with two months still to come. Through September, the last month with settled counts, lateral moves were up 10.1% on the same months of last year, from 10,560 to 11,628. Openings show no such climb.

For planning, treat a new office as a rare event across the market: about 123 announcements a year. A firm that opens one will be noticed by the lawyers it wants to recruit, and by the competitors who will try to keep them.

The same public announcements carry the contrast. Firms published 3,649 hire announcements in the 12 months, and that category rose 5.6% on the year. Office openings, at 123, did not rise with it. That works out to 29.7 hire announcements for every opening announced.

New practice launches, another way a firm signals expansion, were also steady: 66 in the 12 months, a count that held flat (+1.6%) on the year. Firms are building practices and offices at an unchanged pace while they hire more people into the structures they have.

In every year of the series, hire announcements outnumber openings by a wide margin: 27.1 to one in calendar 2025. The practical reading for a firm deciding how to grow is that its peers add people to existing offices first and open new ones sparingly.

Breadth tells the same story. 1,291 firms hired at least one lateral lawyer in the 12 months, 10.5 for every office opening announced. Even if every opening came from a different firm, the large majority of active hirers grew without announcing a new office.

Relocation is part of ordinary lateral traffic: 20.5% of lateral moves also involved a change of city. Lawyers cross cities to join firms, and a firm can draw on that flow for any city where it already has a desk. For a firm already present in a market, the rival for its next partner hire is more likely an established office nearby than a firm arriving with a new one.

A new office needs lawyers on day one, and those lawyers come from the lateral market. That market is busier than a year ago. Partner moves rose 8.4% on the settled windows, which means more firms are bidding for the same senior names that an opening would need as anchors. A firm that announces first and recruits second competes for those partners in public, against offices that are already hiring in the same city.

The order matters. The firms behind the 123 openings of the past year announced into a partner market that rose from 3,558 to 3,858 moves. Securing anchor partners before the announcement keeps the terms private and the timetable in the firm's hands.

Sartori & Partners data show a market that is hiring more, opening offices at an unchanged rate, and building new practices at an unchanged rate. Four consequences follow for a firm's leadership.

First, competition for laterals is rising inside existing markets. With lateral moves up 9.0%, a partner search in a city where the firm already sits should allow for more rival bidders and firmer terms than a year ago. Second, an opening stands out. With about 123 announced in a year, a new office is a visible event, and the recruiting campaign should be ready before the press release. Third, staff the opening from the lateral market before announcing it: the anchor partners decide whether the office is credible. Fourth, a new practice can be a lighter route to growth than a new office; firms launched 66 of them in the 12 months, a pace that stayed flat, and each draws on the same lateral pool without a lease.
